中国历史取水量数据集（1990-2015）

提供中国1990-2015年农业灌溉、市政、工业生产、畜牧业、一次能源开采、发电六个部门取水量的空间分布，空间精度为0. 5°，地理坐标系为WGS84。数据来源于JGCRI论文数据集，对原始数据进行时间线性插值、中国区域掩膜提取以及坐标系转换后得到历史均一化中国取水量数据，以geotiff文件格式保存。历年数据的方法、标准一致，覆盖范围完整，采集处理过程可溯、可靠。本数据实现了现有数据产品的均一化，为分析人文要素规律、人文要素和自然要素的相互作用机制提供基础。

This dataset presents the spatial distribution of water withdrawal across six sectors in China from 1990 to 2015, namely agricultural irrigation, municipal, industrial production, animal husbandry, primary energy extraction, and power generation. It has a spatial resolution of 0.5° and uses the WGS84 geographic coordinate system. The raw data is sourced from the JGCRI published dataset. After conducting temporal linear interpolation, mask extraction for the Chinese territory, and coordinate system conversion on the original data, we generated the homogenized historical water withdrawal data of China, which is stored in GeoTIFF file format. The methodologies and standards adopted for each annual dataset are consistent, with complete coverage, and the entire data collection and processing workflow is traceable and reliable. This dataset achieves homogenization of existing data products, serving as a fundamental basis for analyzing the patterns of human-related factors and the interaction mechanisms between human and natural elements.
